I'm doing with CHO K1 and CHO dhfr-, but I don't have much information about them. I want to know their origin, biochemistry and physiology. If someone know webs or aticles, etc...about them, would you mind sharing with me ?Thank you very much PS: wishing to hear from you soon

Thanks to jonmuoltonTo einstein: CHO is chinese hamster ovary, a commercial cell line for producing pharmaceutical proteinsBy the way, I have a question: There are many kind of CHO (eg. CHO K1, CHo dhfr-) available commercially, but they all lack of biosynthetic pathway of proline. Why isn't CHO which can grow in medium no proline used ?

Oh, I think your idea may be possibly right. I don't know whether CHO really is popular cell line used on the wold beacause I've found it very much but what I gained is little than I expect. Can you see me any lab doing with this cell ?
